.To all whom it concern: Be it kno. that I, JOSEPH N. GRENIER, a

citizen ofthe United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain newand useful Improvements in Skylights, of

which the following is a specification.

EQ- My invention relates to skylightsfor buildings and has for one of its objects the improvement of .the. construction of the'supporting bar which is of the inverted jchannel eam type by providing amintegral drain .or

Iis t ateach side, a'dr'ain or gutter cenfcntr glass fplates, said cushion comprism a tube' sidesof the drain so that the head having converging sides, and a'; lon 'tudina groove at eac gutterto receive a cushion for the metal such as lead. The fasten the ca in place are secured in holes in the centra drain and have nuts thereon,

with beveled side's-to. fit the convepgirlig o t e bolt is drawn into thehole 'in the drain to make a water tight joint. j

- Another ob'ect of my invention-is the provement of the metalcaps used for covervyby forming them with a curved base portion --to seat on the lasswhich before installing Sin osition isma e a substantiallyweathenproof .connec ed with putty or cement to v tion between the glass ,platesand the cap.

The 'rting beams or bars 1 of my 1mprovedsky i tare, as shown, of the inverted lbeam-typeand are provided with a longitudinal gutter-.2 .at each side formed integral .with'thebamn '1 and'having slanting outer'sidesfi; Theto of the beam has a drain or; tter -forme therein and running longitudinally-of the center of the bea h Specification of Letters Patent.

6 indicates a longitudinal groove 01 depression at each side of drain 4. In practice the beam just described canbe made the most economically by rolling but sides of said .drain or gutter being slanting" 'it can-be made in any other manner desired."

The groovedportions Got the beam or bar. 1 have the metal cut out on three sides and turned upat intervals as shown at 7 to form abutments against which rest the lower edges of the plates of glass 8 which constitute the 'surfaceofthe skylight.

9 indicates lengths of soft metal tubing i resting -on the grooved portions 6 between the abutments 7 on which the inner surfaces 1 of the glass plates 8 rest. -The surfaces of'the glass plates used in constructing skylights are unevenand by having the cushions made of tubes of soft metal, as stated, the unevennesses of the" glass plates impress themselves on the surfaces of the tubular cushions so as tomake a water tight joint between the Y glass. plate and cushion and prevent rainv Water, that maycpercolate through the joints,

from'following the inner surface of the lass,

' mg the longitudinal joints of-the glass plates the center gutter.

" The caps 10' forcovering the joints over the beams or bars 1 are formed with integral base portions 10 curved slightly upwardly from the glass plates and before being placed position filled with putty, cement or other filling 1 1 to make-a weather proof j oint. The caps 10 are 'held in positionby -means of screw bolts 12 secured in holes-in the bottom form a water tight joint with the holes, the bolts being held in ositio'n by means of nuts 14' having bevele sides 15 to fit the conglass plate below the transverse joint then' ent at right angles downwardly between the abutment 7 and the plate of glass as shown at 19, then at right angles upwardly under the lower surface of the u' per plate as shown at 20, then back on itse as shown at 21 beyond the joint between the plates. This nm-tion of the transverse bait extends the full so but to follow the top of the beam or tel into 9d. oiidrain 4 which have beveled heads 13 to width of the platesof lass and the parts and 21 rest at each end on the tubular cushions 9 sons to support the transverse edges of the glass plates 8. The lower edge of the flat portion 18 is bent downwardly as shown at .18 to prevent the portion 16 from buckling. The part 21 is cut out as shown at 21 to avoid the abutment 7 and extended back thereof, then cut away 'as shown at 22 to avoid the edge of the beam when bent downwardly as shown at 23 at right angles to part 21. The metal is then bent upwardlyas shown at 24 on a plane substantially parallel to the portion 21 and then obliquely upwardly as shown at 25, the parts 23, 24 and 25 forming a drain or gutter to catch the water-of condensation that forms on the in-,

5 plates, and follow down the inner surface of the glass and the cushion 9, into the drain to be carried Oflu The lowermost transverse drains are formed of continuous plates of sheet metal bent to form an u right portion 26, then bent at right angles t ereto as shown at 27, then bent downwardly between the lowermost abutment 7 and the lower ed es of the lowermost glass plates, then upwar ly at right angles as shown at 28 between. the inner edges of the plates of glass and the cushions 9, then back on itself as shown at 29, the parts 28 and 29 extending the full length of the plate of metal to form ri id cross bars to support the lower edges of the glass plates. The parts between the beams 1 are cut away and bent downwardly as shown at 30 then upwardly as shown at 31 and finall obliquely u Wardly' as shown at 32 to form t e drain. T 1e edgesofthe parts 31 are bent downwardly as" shown at 33 to form integral lips to direct the water from the drains formed bythe parts 30, 31 and 32 into the drains 2.

, The upper ed es of the uppermost plates of glass are hel in positiorr y means of a clamping member made of sheet metal having a portion 34 to lie on top of the plate with its lower edge .bent downwardly as shown at 35 to prevent buckling. The metal is bent downwardly at right angles to part 34 as shown at 36 along the upper edge of the glass plate, then at a right angle as shown at r 37 under'the upper edge of the glassplate then back on itself as shown at 38 and finally downwardly as shown at 40. The parts 37 -made of inverte and 38 form a rigid cross-bar to support the upper edges of the plates of glass 8.

From this descri tion of my invention it will be apparent tiat all condensation of moisture that forms on the inner surfaceof the glass lates are taken care of by the cross bars or out by means of 'the'cement orputty 11 but should a leak occur between the caps 10 and the lass plates'S the water will be caught by the drain 4 and carried off, the tubular cushions 9 as stated above preventing the water from creeping along the inner surface of the plates. Also as each late of glass is supported by means of the a utments 7 the weight of the skylight is evenly distributed over the supporting beams 1 and the lower plates relieved of the crushing weight of the upper plates of glass.

have shown and described the cushion 9 made of a tube of soft metal such as lead but it will be understood that I can use a solid bar of any soft metal as lead or its like as shown at 9 in Fig. 4 without altering the spirit of my invention.
